Continuity mistake: After chasing down Sully, the yellow Porsche is totally wrecked on the left side, until Arnie drives it away, and it's fine. Later, when Arnie and Cindy arrive at the hotel, the car is wrecked again. (00:39:50)
Continuity mistake: When Matrix is driving the red car and trying to run Sully's yellow car off the road, watch the front bumper of the red car. At some points it is hanging off the car, and at others is it attached onto the car. (00:39:50)
Continuity mistake: At the very end of the film. When the 3 helicopters and the seaplane come into land, it is quite a wide shot, with no boats visible. A few minutes later, when the seaplane takes off again, a big white boat is near the coast. Even if the boat was off camera during the landing scene, a few minutes was surely not enough to get that far, and that close to the shore. (01:20:30)
Revealing mistake: When Matrix hits the button to blow up the village, you can see that there are only cardboard stand-ups of men next to the buildings blowing up. Also, for some reason the top of the watch-tower also blows up even though Matrix never put a bomb there. (01:11:00)
Visible crew/equipment: When Matrix is holding Sully over the cliff, you can see the cable holding him up. (00:40:51)
Continuity mistake: At the start of the film we see two guys on the bin wagon. The one on the left of the screen already has his Uzi in his left hand, yet in the next shot we see him lean into the back of the bin wagon to pick it out. (00:01:45)
Continuity mistake: When Bennet and Matrix are fighting at the end. Bennet has his hand over Matrix's face. During instant camera cuts, the position of his hand alters on Matrix's face and neck. (01:18:55)
Continuity mistake: Rae fires a rocket at the police van, first she fires it back to front then the second time she fires it correctly only this time she is knocked back by the recoil, why wasn't she affected the first time and pushed forward? Also there should be no recoil with a rocket launch. (00:57:10)
Suggested correction: She was pushed forward against the front windshield which kept her upright whereas when firing it the right way she was thrown backward into the back seat. And rocket launchers will have some measure of recoil from the propulsion of the rocket firing out of the front of the launcher, how much depends on the time and force of the rockets being firing as every weapon has some form of recoil from firing.
Rocket launchers don't have the recoil you think. The propulsion of the rocket firing out of the front is countered by the gases expelling out the back behind the shooter. But if she was pushed forward (which she's not), her waist was above the top of the windshield, so the top of her body would should still lean over, even if it didn't cause her to topple over like she does with the seat.
Continuity mistake: At the end of the movie, Arnie puts on his flak jacket then his make-up, but when he takes off his jacket, he's got camouflage on. (01:04:15 - 01:14:40)
Continuity mistake: When Arnold lets go of the landing gear he lands in the water. A few seconds later we see him walking up towards the beach, and we can now see that he is only wet from his waist down. It's not likely that he would have been able to land standing on his feet and not not becoming completely soaked. (00:24:41)
Continuity mistake: When Matrix first rips out the seat of Cindy's car and sits in its spot, his body sits very low to the the bottom of the car. You can even see in the next scene that his head is clearly lower than Cindy's. However, during the chase scene, his head is level with Cindy's. (00:29:55)
Continuity mistake: When the baddies are destroying Matrix's house he is laying on the floor covering his daughter's head. The position of the hand keeps swapping depending on the angle. (00:11:50)
Continuity mistake: After Matrix throws the police officer into the bunch of officers at the mall, he runs at Sully, and you see the guards are beginning to get back up on their feet, but then you see them again a few seconds later, and they are back on the floor again! (00:36:27)
Visible crew/equipment: When Matrix and the girl are driving out of the parking lot you can see the camara crew in the reflection of the car. (00:29:54)
Revealing mistake: Just before the guard in his tower gets killed and falls out, you can see the wooden sides have been precut. When he supposedly falls through the wood it parts along the cut line but remains hanging on string. (01:10:48)
Continuity mistake: When Matrix jumps inside the house to protect the girl from the shootings, the blood stain on his forehead suddenly disappears. (00:12:00)
Continuity mistake: When Cindy fires the rocket launcher she is knocked down by the blast. The camera cuts to the rocket flying to the van and she is instantly stood up again. Slow-mo may be helpful but is not essental. (00:54:50)
Revealing mistake: During the scene where Matrix is attempting to push his truck down the hill, pay close attention to the shot where the truck starts rolling and Matrix jumps into the cab - the cable controlling the truck is visible to the right of the rear tire. (00:14:10)
Continuity mistake: In the bar at the mall, when the bad guy receives the money and handshakes the fat man, he grabs a glass with his left hand. In the next shot his hand is suddenly away from the glass. (00:33:20)
Other mistake: When Matrix is rowing the raft towards the shores, if you look behind him, he is clearly rowing the raft towards open sea, with no island in sight. (01:06:13)
